Remote Programming

Time Base Commands

The TIMebase subsystem commands control the reference clock source of

the DSP.

:TIMebase:REFClock

Command

:TIMebase:REFClock{INTernal|E100}

Description

The command selects the reference clock source.

INTernal

Internal 10 MHz reference oscillator (default)

E100

External 100 MHz reference

The following errors are detected, when an external reference clock source

is selected:
• Amplitude of external reference signal too small or no signal.
• Frequency of external reference signal out-of-range.

These errors are reported in the STATus subsystem. After selecting a new

reference clock source, the status should be queried. In all these error

cases the external reference signal is not usable, and the module

automatically selects the internal reference oscillator.

Query

:TIMebase:REFClock?

The query returns the currently selected reference clock source.

Returned Format

[:TIMebase:REFClock] {INTernal | E100}<NL>
